[. . . ] Amber means the Powered Subwoofer amplifier is in "Standby" mode and will power-up and operate as soon as a signal is fed to it. Red indicates an amplifier-fault condition. The light goes dark when the Power switch is in the "Off" position. The Powered Subwoofer amplifier is disconnected from the AC line in this condition. The Slave Subwoofer connects to the Powered Subwoofer with the supplied 25 foot 16-gauge speaker cable (or any other high quality heavyweight speaker cable). · Using the supplied wire strippers, remove 1/2 inch of insulation from the copper and silver colored wires at each end of the speaker wire. Twist each exposed lead's fine wire strands tightly together. · Remove the cover from the "SLAVE SUBWOOFER OUTPUT" on the back of the Powered Subwoofer. Connect the coppercolored wire at one end of the speaker cable to the red (positive) connector on the Slave Subwoofer speaker output. Connect the silver colored wire to the black (negative) connector. · Connect the opposite end of the speaker wire to the Slave Subwoofer input connector in a similar fashion. · The information about placement on pages 5 and 6 also applies to the combination of a Slave Subwoofer and Powered Subwoofer. While it is often convenient to place the two units right next to each other and treat them as one, they will couple acoustically even when they are placed several feet apart. Slave Subwoofer Powered Subwoofer SLAVE SUBWOOFER OUTPUT 4 Placement Before connecting your Powered Subwoofer, place it in your listening room using the guidelines that follow. Once your sound system is operating with the Powered Subwoofer, listen and experiment further with placement before making the installation permanent. The ear cannot localize the very low bass sounds reproduced by the Powered Subwoofer. This is why it is possible to use a single powered subwoofer to reproduce all the 25 to 40 Hz bass a sound system requires. It is also the reason why the subwoofer need not be located particularly close to other speakers or aimed directly at the listeners. The Powered Subwoofer should be positioned vertically (stick-on feet are provided for attachment once you have decided on its final orientation). It can sit in a variety of positions within the listening room, although we don't recommend placing it behind listeners. Also, do not place the Powered Subwoofer underneath furniture. Make sure there is a clear air space of at least 18 inches surrounding the Powered Subwoofer. Don't place objects on the Powered Subwoofer (such as clothing) that could inadvertently drape down the front or back of the unit, restricting air flow or speaker output. [. . . ] There are no other fuses or userreplaceable parts within the Powered Subwoofer. Do Not substitute a fuse of a different rating. Difficulty? IMPORTANT: Turn off and unplug the subwoofer before changing the fuse. If you suspect a problem with your subwoofer, contact the store where it was purchased. If a problem is confirmed, you will need to return the speaker to that store or its Authorized Service Center. If you purchased the speakers through our mail order catalog, by phone or via our website, call 1-877-YES-HIFI. [. . . ]
